The RK4-2302 is powerful and versatile enough to handle a wide variety of on-the-run assignments like fashion, corporate work, portraiture, weddings and interiors. Having 2 power packs as lightweight as these gives you the positioning flexibility of monolights with multi-head (6 total) capability. If you locate the packs in the same room you can trigger one via the included 16′ sync cord while the other fires via its built-in optical slave. With an optional IR transmitter you can trigger both packs with their built-in Wein IR slave. For long distance triggering, optional radio remote systems like PocketWizard are available.

The RP400 pack has 3 head outlets and breaks down its output symmetrically or asymmetrically over a 6 stop range with short flash durations at a super fast 1.0 seconds recycling time at full power. A variator knob allows fine tuned exposure adjustments over 2 stops in 2/10 stop increments.

The included MH2015 flash heads have a 250W modeling light, 16′ power cable, user replaceable 2000W/s capacity flash tube and an ideal color temperature of 5400K. Fan-cooling means that you’ll get extended life out of both the flash tube and modeling lamp.

Although you may be tired at the end of a long shooting day, it won’t be because of your equipment. The RP400 pack weighs a mere 4.1 lb and the MH2015 flash heads about 2 lb each
